Is this what is being sent now, or was this just a shipping mistake?** A: Mine came in a clear plastic case with a black plastic divider section. Not the greatest however I needed the bits to work, not the case. **Q: I want to drill 8 to 10 holes through large, stainless steel hinges (3mm thick).Could I do the job with these drills?** A: Probably but you will need the right cutting fluid . I did not use this bits on SS yet. Thank you GOOGLE: "What can you use to cut stainless steel fluid? As a manufacturer of metal processing oil, we recommend MORESCO BS-6M soluble cutting fluid, MORESCO BS-9 soluble cutting oil. WILL CM-128 semi-synthetic cutting oil, WILL CH-370 semi-synthetic cutting fluid. These cutting oils are especially good on stainless steel, and provide excellent performances during machining." **Q: Is this suitable for the soft metal in jewelry?** A: yes, any metal **Q: Where are they made?** A: Unfortunately I could not find a country of manufacture this company. They are inexpensive bits, and I've had good luck with them. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Drillability *by T***R on May 19, 2025* I went through 3 other bits to drill 5 holes in a steel utility trailer. Then ordered these drill bits. I drilled over 30 holes in same steel trailer frame using one ONE of these drill bits! Still remained sharp. Remember to use alittle oil when drilling. Seriously, these drill bits are great!! ### ⭐⭐⭐⭐⭐ Great value *by D***N on May 11, 2025* Nice set of bits. Sturdy container too. ### ⭐⭐⭐⭐ Missing bits *by F***V on May 22, 2025* Box is sturdy and packaging material was well protective of the product. Downside is there are 4 bits missing from the box, pictured. Sizes 1 to 2.5 are not there. I've tried shaking the box a bit but doesn't seem they're lost in there, either.Unfortunate, but the rest of the bits look great. ## Frequently Bought Together - Cobalt Drill Bit Set 6mm - 10pcs, M35 Twist Drill Bits Straight Shank, 6mm High Speed Steel Drill Bits for Drilling in Hard Metal, Stainless Steel, Cast Iron - Owl Tools 7mm Cobalt Drill Bits - 13 Pack M35 Cobalt Drill Bits with Storage Case - Perfect for Metal, Hardened & Stainless Steel, Cast Iron - M MIMHOOY 5mm / 0.19" Cobalt Drill Bit Set (10 Pcs), M35 Cobalt Twist Drill Bits for Stainless Steel and Hard Metal --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/503362676-cobalt-drill-bit-set-6mm-10pcs-m35-twist-drill-bits](https://www.desertcart.pl/products/503362676-cobalt-drill-bit-set-6mm-10pcs-m35-twist-drill-bits) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
